The Amethyst" Series of studio microphones utilize capsules with 6-micron gold sputtered Mylar diaphragms tensioned and adjusted on precisely made brass backplates. They possess very fast impulse transient response without sound coloration or low frequency reduction, as well as the ability to handle louder sound pressure levels.

"The Amethyst Standard" has a dark amethyst red body and uses a single large-diaphragm center-terminated capsule to provide a modern, detailed sound with airy highs, medium vocal presence and accentuated low-end response. The internal phantom powered preamplifier is a fully discrete Class ’A’ transformerless circuit which provides high output, flat audio response and ulta-low distortion and noise.

"The Amethyst Vintage" has a grey/blue body and uses a dual large-diaphragm, center terminated dual back plate capsule which provides a classical, wide-spectrum, vintage microphone sound. Both models have a unidirectional cardioid polar pattern with minimal proximity effect and are linear over the wide frontal incidence angle. An acoustically transparent head construction reduces internal resonances and reflections. The internal capsule shockmount along with the massive body construction, reduces stand rumble, outside infrasonic interference and mechanical shocks.

Both microphones can be mounted directly on a standard microphone stand or in the optional ASM elastic shockmount. Gold plated contacts on the output XLR connector provide a noise-free connection.
